' To all whom it may concern: a

' Be it known that 1, CHARLES P. Mosnna, a citizen of the United States, and resident of Syracuse, inthe county of Onondaga and State of New York, have invented certain new and. useful Improvements in Typc-Writing Machines, of which the following is a specification.

My invention relatesto typewritin mochines and more particularly to tabu ating and to margin stop mechanism.

The object. of said invention isto provide efiicient mechanism of-the character speci- '29 claims In the accompanying drawings wherein like reference characters designate correspondin parts in the various views, Figure 1 is a si e, elevation, with parts broken away,

of one form of typewriting machine embodying my invention, sufiiclent number of parts of a typewriting machine being shown to illustrate my invention in its embodiment therein. Fig. 2 is a front elevation of the same with parts sectioned away. Fig. 3 is an enlarged detailsectional view showing theescapement wheel and some of the associated parts. I Fig. 4 is an end view showing some of the parts illustrated in Fig. 3. Fig. 85 5 is a diagrammaticfront elevation showing the 'escapement wheel and pinion and oertain' of'the tabulatorstops. Fig. 6 an enlarged detail, fragmentary, side elevation with parts sectioned away, showinga ortion of the releasing mechanism for enab ing the margin stops to be released. F ig. 7 is a fragmentary, detail plan view showing some of the parts illustrated in Fig. 6. Figs. 8 and 9 are detail perspective views of the-stops carried by the frame of the machine. Fig.

10 is afragmentary detail perspective view showing the carrier fOl'illO stops illustrated in ,Figsh and 7. Fig. 11 is a diagrammatic perspective view ofcertain of the stops to 5 be hereinafter described. Fig. 12 is a detail front view showing a modified form of con-- struction forelevating the stops during the travel of the carriage.

While I havefillustrated iny invention in a front strike machine, it'will be understood that the invention may be embodied in va- -rious styles of typewriting machines.

The frame of the machine comprises a base 1, corner posts 2 and top plate 3. Fixed guide rails 4 are mounted-on the top plate of the machine, he upper rail being carried by brackets 5. he guide rails are rooved on opposite sides for'eoiip'eration with antifriction balls or rollersfi which are likewise received in oppositely. grooved faces of a rear uide bar 7 which constitutes. the rear cross or of the carriage. End bars8 project forwardly from the rear cross bar 7 and are ',aperture to receive a platen shaft 9 which supports a cylindrical platen .10. The carriage 18 thus mounted to, move in the usual manner from side-to side of the '1na.-

chinoacross the to plate. Arms 11 extend rearwardl from t e crossbar 7 at or near the ends t ereof and sup ,ort a feedrack 12. This rack has downwar 1y rojectinggear teeth 13 for cooperation with a feedpinion 14 fixed to or forinin part of a sleeve 15, as shown in Fig.3. A s iaft 16 extends through the-feed pinion and its sleeve and is provided at its rear end with a disk 16. An escapeinent rack, which in the present instance iscircular or in the nature of an escapement wheel 17 turns freely on the shaft 16 and bears at its r'ear side against the disk 16. The disk 16 is provided with a bearing 18 f0. cooperation with a coned bearing screw 19 carried by a bracket 20 secured to the to) late of the machine. The forward end o the shaft is likewise provided with a bearingfll for cooperation with a bearing screw 22 carried by an upright bracket arm j or post 23 secured to the top plate.

The forward side of the escapemcnt wheel is provided with clutch teeth 24which ensplined groove-29 so as to connect the feed a 28 to turntogetherand totafiord a moveend of the clutch section 2 6 and at its op- -ment wheel and thus connect the escapethe nature of a rock shaft which extends bemally maintain the re ease key 37 in. the

festive to elevate the bar 33, thus cumming I ner to effect a'step-by-ste forward feed of -by'a dog rocker 43 pivote at 44 on a motion and .arrestit and therparts connectspring being anchored in an opening in an pinion and the clutchsectionflfi and cone ment of the clutch section 26 toward and away from the teeth 24 of the companion clutch section on the escapement wheel. A coiled expansion spring 32 surrounds the sleeve 15 and-bears at one end against the osite end against the feed pinion so as toorce the clutch section 26 to engage the companion clutch section on the escapement and thus connect the escapement wheel to'the feed pinion. An inclined bar 33 extends throughoutthe length of the carrings and cooperates with the coned face of the member 28. Thisbar is carried by downwardly an'd rearwardly extending arms 34 pivoted at 35 in the end plates of the carriage, one of the pivots 35 bemg'm yond' an end plate of the carriage and is rovided with an arm-36 terminating in a nger piece or release key 37. A stop pin 38 pro ects from one of the end plates of the carriage into the path of the associated depending arm 34 to limit-.itsgdownward ed therewith in their movement to normal position. A coiled spring 39 (see Fig. 2) 18 connected at one end as indicated at 40.to one of the arms 34, theiother end of the adjacent end plate of the came e. The pressure of this sprin is exerts to norelevated position and to.maintain the rerelease bar 33 in the position shown in Fi 1. A depression on the release key is e theclutch section 26 forwardly against the i'essure of the spring 32, thereby disengagmgthe clutch to free the carriage from the escapement wheel. Feed dogs 42 e063 'erate with the escapement wheel in the usua manthe carriage. These fee do s are carried the sto 5 may be situated if desired a letter space istance apart, as indicated in Fig. 9. I

These stops pro ect varying hei h ts or vs ing distances from the stop %ar and. t c stopping portions 52 are all arranged in the same vertical lane, but traveling in' differ-5 ent paths. T 'e lower ends of these stopsare provided with inwardly directed rojections 53 to contract the opening 54 a jacent to theprojections so that the distance between the projections will. be less than the thickness of the body portion of the .75 bar 12. From'an inspwtion of Fig. 1 it will be seen that the length of each oft-he openings 54 in the stops is greater than the height of the bar 12 at that portion thereof which carries the teeth 45, in order that the stops may have a free up-and-down movement on the bar 12 in the interdental spaces for a limited distance, the upward move ments of the stops being limited by the inwardly directed project1ons53 thereon engaging the body portions of the .2 112. The sto 5 may be adjusted to various points along tie stop bar 12 by slightly spreading or springingthe arms forming the bifurcated portion of each stop a art so that the projections 53 will clear t e body por- 'tion of the bar, when the stops may be withdrawn from the bar and adjusted to different points along the same. By rounding the projections 53 in the manner'shown in Fig. 9 they may act as cams to force the arms apart when'the stops are moved up# wardly with unusual force, thus facilitating .the removal of the stops. In a like manner the rounded corners of the rojections 53 10 may be effective to separate t e arms when lacing the stops in position on the stop From the foregoing descriptionit will be understood that the bar 12in addition to 10 constituting the feed rack for the carriage likewise constitutes a stop bar for the tabulator stops. This her also constitutes asto carrying bar for margin stops '55 and 5 the stop.56 limiting the movementof the '11 carriage from left to ri ht and the stop 55 limiting the movement 0 the carriageto the left, as will hereinafter more clearly appear. The bracket arm or post 23 constitutes a support for guiding a stop-carrying mom- 11 her, designated as a whole by the reference numeral 57 and shown in detail in Fig. '10. This stop-carrying member may be made of' sheet metal and is provided with a rtion' 58 whichpartly surrounds the uprig t post}.

23 to guide 'the member 57 in its upand do'wn movements and to form a firm supporttherefor to resist the impact oi the carriage.

Stops 59 and 60 are received within an'opening (i l in the stop carrier 57 and-project dow'nwardly beyond the lower edgeof that portion ,of the carrier in which the opening 61 is provided. Across pin or rivet 62 extends fr m side to side of the carrier 57 to confine 2nd guide the stops 59 and 60 in 1 wise overlaps the side of the stop carrier 57 to limit the downward movement of the stop 60 with reference to its carrier. A leaf is rin' .65 is secured in place by a screw 66 tiirea ed into an opening 67 in the stop car rier. This spring is a double spring, as

shown in Fig. 2, one arm thereof pressing downwardly upon the stop 59 and the other pressing downwardly upon the stop 60 to normally maintain the stops 59 and 60 in fixed relation with reference to the stop carrier 57. A shouldered screw 68 passes through a slot 69 formed inKt-he upri ht stem 70 of the stopcarrier 57, the three ed end of the screw being received in a tapped 0 ing in the guide post or bracket 23. In

t is manner the stop carrier is effectively guided inits vertical movements. The stop 59 has a depending engaging portion 71 in one vertical plane and the stop 60 base dei, pending engaging portion 72 in anothenparallel vertical lane. The stop 59 on its righthand face is at, the en aging portion being a. flat vertical face,,w ereas the opposite face of the engaging portion is beveled as indicated at 73. On the other hand, the deending engaging portion 72 of the stop 60 has its left-hand face in a vertical plane as indicated at 74 whereas the right-hand face of the engaging portion is beveled as-indicated at 75.-

A sheet metal slide or releasing member 76 is provided with arms-77 which straddle the carrier 57- and is formed with a depend.- ing stem 78 whichyas shown in Fi 6, is

,slotted at 79 to.receive a shoulders screw- 80 to connect the sheet metal releasing slide 76 to the depending actuatin arm 70 of the ing such that the releasing member 76 moves up and down with the sto carrier 57 but is free to receive plate of the machine an is arranged above c an actuatm cam 83 carried by a crank arm 84 on] a. r 'shaft 85 mounted in bearings -l on the'top plate of the machine. The rock shaft 85, as will be seen from an inspection of Fig. 2, terminates at its inner end where it carries the cam about midway of the machineand extends to the right-hand end of the top plate where it is provided with a crank arm 86 to which an actuating rod 87 is connected. This rod is mounted at its forward end to move in a bearing opening in a bracket 88 secured bya screw 89 to the top plate of 'the'machine. The rod is pro- -vided at its forward end with a key or finger piece 90. A coiled s ring 91 surrounds the actuatin rod 87 an bears atone end against the liracket 88 and at its opposite end against the finger piece 90 to maintain the rock shaft and the parts connected therewith in the normal position shown in nism is moved rearwardly the rock shaft 85 is turned,-thus effecting an upward and rearward movement of the cam 83 around the axis of the shaft 85. The effect of this movement is to bring the cam into engage: ment with the lower end 81 of the stem- 78, thereby elevating the stem and movingthe releasing device 76 upwardly. From an inspection of Fig. 1 it will be seen that the arms 77 are situated beneath the pins 63 and 64 on the stops 59 and 60 respectively, so that an upward movement of the releasing device or slide 76 is effective to move the stops 59 and- 60 upwardly in the stop carrier against the pressure of the spring arms 65. This upward movement of the stops 59 and 60 by the releasing device'is effective to move said steps out of the paths of the margin sto $55 and 56, as will hereinafter more clear y appear. From an-- inspection ofFigs. 1 and 5 it will be seen that the lower ends of all of the stops which are carried by'the combined sto carrying bar and feed rack 12 are situated so that they will be brought into contact with the teeth of the feedpinion l4 during the travel of the carriage, and during the rotation of,the feed pinion, and as the teeth of the feed pinion move u wardly they are engaged successively y and are effective to slightly elevate the stepson the stop-carrying bar, and the stops are thus all successively and automatically elevated during the travel of the carriage. The successive upward movements of the stops effected by the travel of the carriage in the manner described are effective to render them operat1ve, as Wlll presently appear, and constitute an important feature of my invention.

From' an inspection of Figs. 2 and, 11 it will beseen that the margin stops 55 and 56 arelonger than the stops 4-6 to 51. The length of the stops 55 and 56 is such that when they are moved upwardly by the co- -.to enable the carriage to move beyond the n fiiinational 5 5 lever 92 is pivoted at 94 to a bracket 95 seto right willheelevated by its engagement with the feed pinion and while in the elevated position will be brought into engagement with the stops 60, whereas the stop 55, which is in the same path as the'stops 46 to 51-,(see Fig. 11) will, when it reaches the feed pinion, be elevated to .coact with the depending enga ing portion of the stop 59. If it isdesire to pass .beyond either of these margin stopsit is simply necessary to push the finger piece 90 rcarwardly; tn etfect an upward movement of th releasing device 76, which movement is e ective to elevate the steps 59 and .60 against the pressure of thes ring 65, thus carrying these stops out of t 1e path of the stops 55 and 56 limit oftravel ordinarilyidefined by the coope'ratiorfof the sto'p,s 55 and 56- with the co-acting stops 59 and" 60 respectively. After the stop 60 has passed to the left beyond its coacting sto 56,-through the actuation of the release ey 90in the manner described, a return movement of the carriage is'efiective, by reason of the bevel 75,

toeleva te the-stop 60 against the pressure of its spring 65, so that the carriageis unobstructed in its movement from left to right. Inv alike manner the stop 59 is elevated againstthe ressure of its spring .65 when the stop 59 as passed beyond its coacting stop 55 and a movement of the carriage from ri ht to left is efi'ected. At this time'the have 73 co-acts with the stop 55, to cause the stop 59 to be elevated against the pressure of'its spring 65.

' As'hereinbefore pointed out, the tabulator stops 46 to 51 may be adjusted as in-.

The means fdi' interposing the stop 59 to select a deposition of arrest and for releasing the carriage consists of a lever 92 pivoted at 93 to t e depending stem of the sto carrier, this stem extending down throug the opening 82 in the top plate to the lower portion of the machine. The

'1 Theforward end of the lever 97is provided wit a finger piece 100 by which it and the le er and parts cori- 55 trolled thereby may'be'tctuated; Ihe lever Z-apartand in thisadjustment of the stops 97 pusseis, through a slot 101 formed in an index plate and actuating device 102. This plate is provided with notches or teeth 103 stops 46 to 51 employed, six being shown in the resent instance. Indices 104 are provide op osite .each of the teeth or notches 103 in 0rd ing the proper positioning of the hand actuated lever with reference to the index plate.

The in ex plate is provided with a rearwardly extending car 107 (see Fig. 1) to whichis pivotally connected at 108 a rearwardly extending crank arm 109 secured to a rock shaft 110 mounted in bearings in the frame ofthe machine. The rock shaft carries intermediate its ends a rearwa'rdly directed crank arm 111 pivoted at 112 to an upright link or arm 113 which extends through an opening in the top 'plate of the machine and is provided at its upper end with a contact shoe 114 which engages the lower edge of the release bar 33. The body of the lever 7 is sufliciently resilient to afford a sli ht lateral movement of the lever at its or- Ward end in the slot 101 of the index plate. A tooth 115 is formed on the lever, the tooth being received in the index plate and adapted to engage the teeth 103 on the plate. The operator to select a proper definger piece 100 slightly to the right to clear, it from engagement with the teeth 103 and then depresses the forward end of the levcr until the tooth 115 is opposite the tooth 103-0n the plate which is to be engaged. The relaxation of the lateral pressure exerted on the finger piece enables the 'tooth 115 to seat itself in the proper notch and engage the tooth 103 which has been engaged in the manner specified, a downward pressure exerted on the finger piece 100 is effective to move the plate 102 downwardly and this motion is transmitted to the arm 109, rock shaft 110 and arm 111, which is effective to elevate the rod or' link 113 to swing the release bar upward movement of the bar 33 cams the member 28 forwardly,

to "5 1 arranged along the stop rod at of the tabulator' stops. The same movement of the finger. iece 100 which released the carriage was e ective 'to elevate the rear end of the lever 97,- thus effecting a corresponding elevation of the right-hand end o'f'the lever 92. This resulted in. ulling down the stop carrier connected to t e left h'and end of the lever 92 and to effect a predetermined extentof downward movement of the stop 39 to bring it into the path of the proper stop 46 to 51-, determined by the coaction oi-t'ae ta' ulating lever 97 with theindex plate" 102. It will be observed that the first part of the motion transmitted to looting movement to the'stop 59 and that this movement takes place before the tabulator lever 97 is engaged with the releasing or index plate 102. The slight additional movement given the lever 97 afterit engages the releasing plate 102 is suflicient to position the stop 59 where it will be in been selected when the said selected stop 46 to 51is elevated to operative position by cooperation with'the feed pinion. It willthus be seen that/it requires the automatic actuation of one of the stops 46 to 51 and the actuation of the key controlled stop 59 to bring about a cooperation of'the tabulatorstops whereasthe automatic elevation of the stops 55 and 56 in itself is 'sutlicient stops 59 and 60. After pressure is released 'on the finger piece 100 a spring 116 is effective to move the lever 97 and the parts connecte therewithto nqrmal- 'osition, the

Various changes may be made without departing from the spirit and scope of my in-. vention. What I claim as new and desire to secure by Letters Patent, iszk 1 1.
